The black widow is a venomous spider with a potentially dangerous bite. The bite may or may not be visible as one or two puncture wounds on the skin. A bite may initially go unnoticed and produce no symptoms. Some people feel pain soon after a black widow spider bite. Black widow spider venom affects the nervous system, and common symptoms include abdominal pain, muscle cramps, weakness, and tremors. Profuse sweating, fever, nausea, vomiting, and difficulty breathing may occur in severe cases.

Symptoms and symptom severity after a black widow spider bite vary considerably. Those with underlying health problems, the elderly, children, and those with compromised immune systems may suffer more severe consequences due to a black widow spider bite.
